The cover is movably engaged with the base and selectively closes the opening. The lift mechanism includes a supporting member adapted for bearing and lifting a fuel container in the chamber to different heights.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a flame device and, particularly to, a flame device including a lift mechanism and can lift a flame to a predetermined height.

2. Description of the Related Art

U.S. Pat. No. 7,097,448 discloses a vortex type gas lamp for producing an upwardly-directed vortex flame of combustible gas inside a surrounding and confined boundary of rotating body of air. An interface is located between the body of air which is devoid of gas and a central region of gas which is bounded by the interface during the operation of the gas lamp. All of the combustion of gas substantially occurs inside the interface. The gas lamp has a central axis and includes a base supplying combustible gas without air at and nearly adjacent to the central axis. The gas lamp further includes a shield including first and second axially-extending sections structurally attached to the base in a fluid-sealing relationship. The first and second sections are substantially identical and transparent to light and each includes an impermeable wall having an arcuate inner surface and an arcuate outer surface. Furthermore, each of the first and second sections has first and second edges extended axially. The gas lamp yet further includes the first and second walls alternately overlapping one another. The first and second walls are adjacent to their edges and are spaced from one another so as to form tangentially-directed ports, thereby forming an axially-extending chamber open at its side only through the ports. Furthermore, the first and second sections are arranged that at the base they surround the entry of the combustible gas and gas receives air for combustion only through the ports, whereby combustion of the gas results in a flame spaced from the inner surfaces and the peripheral body of air is devoid of gas entering through the ports. Generally, if no air is supplied for combustion, a flame will be put off. Unfortunately, it is not easy to preclude air from entering through the ports. Additionally, the shield is hot and it is not safe to place a covering member in each of the ports.

Furthermore, U.S. Design Pat. No. 621,873 discloses a fire tornado lamp including a base, and a shield. The base includes a plurality of ports disposed circumferentially. The shield is transparent to light and hollow, that is, it includes a passage extended therein. The base and the shield are connected to each other, and each port extends radially with respect to the passage defined in the shield and communicates therewith. In addition, each port is so configured that it induces air into the passage in a direction substantially tangential to a circumference of the passage. Likewise, it is not easy to preclude air from entering through the ports and not safe to place a covering member in each port.

The present invention is, therefore, intended to obviate or at least alleviate the problems encountered in the prior art.

SUMMARY OF THE INVENTION

According to the present invention, a flame device including a lift mechanism and can lift a flame to a predetermined height includes a base, a cover, and a lift mechanism. The base includes a chamber including an opening. The cover is movably engaged with the base and selectively closes the opening. The lift mechanism includes a supporting member adapted for bearing and moving a fuel container in the chamber to different heights. Fuel is adapted to be contained in the fuel container. Flame is produced after igniting the fuel. The lift mechanism is operably movable in a first direction including the supporting member being moved up from a lower height to a predetermined height and in a second direction including the supporting member being moved down from the predetermined height to the lower height.

The supporting member is lowered from the predetermined height to a height in which the fuel container is able to be replenished with fuel or replaced.

It is an objective of the present invention to allow a user to safely ignite the fuel and to facilitate the removal of the fuel container.

Other objects, advantages, and new features of the present invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanied drawings.
